SPECIFICATION forming part of Letters Patent No. 682,21 1, dated September 10, 1901. Application lilecl December 10, 1900. Serial No. 39,396. (No model.)

To r/JZZ whom it may concern:

Be it known that I, EDMUND B. LUDWIG, a citizen of the United States of America, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Apparatus for Making Illuminating-Gas; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others t-o make and use the same, reference being had to the accompanying drawings, forming a part of' this specication.

The objects of my invention are, iirst, to obtain an admixture of the air and gas in definite proportions and facilitate such admixture; second, the distribution of the gas for consumption under pressure, and, third, the automatic regulation of the generation of the vaporized iiuid in proportion to the amount of the mixed gases consumed.

The invention consists in the novel construction and combination of parts, such as will be first fully described, and specifically pointed out in the claims.

In the drawings, Figure l is a View in elevation of the improved apparatus. Fig. 2 is a detail view in perspective of the air and gas mixing receiver, with parts broken away to show the separate compartments and separate diaphragms and heating-tube. Fig. 3 is a vertical sectional view of the gas-burner.

Similar letters of reference indicate corresponding parts in all the figures of the drawings.

Referring to the drawings, A represents a hermetically-sealed tank for the reception of uid, such as gasolene, of which ais the top, ct the side, and a2 the bottom. Through the top a, of the tankA is extended one end of a delivery-pipe B for the duid, which end extends downwardly to within a short distance of the bottom 0.2 of said tank. The upper end of pipe B extends upwardly a short distance above the top a of the tank A, and with said end is connected a four-way pipe-joint b. From the opposite sides of the pipe-joint b extend the branch pipe connections b b2, which are bent at right angles and extend upwardly the proper distance, the branch h2 extending nearly twice the height of the branch b. From the upperpart of the four-Wayjoint b extends Directly above the branches b' b2 b3 of the i pipe-joint b is the air and gas mixing receiver C, which consists of a cylindrical shell of considerable length and having the ends c c. The interior of the shell or receiver C is divided into three compartments c4 c5 c(i by the two circular plates or diaphragms c2 c3, which are connected transversely with the inner side of the receiver and arranged in position at an equal distance from the respective heads or ends c c of the receiver and at a corresponding distance apart. Near the bottom of receiver C and lower part of the diaphragm c2, separating the compartments c4 c5, are several perforations c7, and in the upper part of the'diaphragm c2 are a number of perforations co. Through the receiver and the compartment c6 in line With the chamber of said receiver extends a vertical gas-heating tube D, which in position is arranged a short distance from the end c' of the receiver toward the diaphragm c3, the ends of the tube extending a short distance beyond the outer side of the receiver. Upon the lower end of tube D is an annular downwardly-extended outwardly-flaring flange d. Vith the bent upper end of the branch pipe b2 of the pipejoint l) is connected in the usual manner one end of a short pipe b4, which extends horizontally to a position beneath flanged on the fine D in receiver() and is connected with the gas-burner E, which is shown in detail in Fig. 3. Said burner consists of a cup-shaped receptacle e, arranged in position Within the annular flange d of the flue D and having a bottom e', in which is an opening e2. With the bottom e' is connected one end of a tube e3, which extends around the opening e2. The other end of tube e3 is bent nearly at right angles to the cup e and extends a short distance therefrom. With the side of cup e is connected the upper end of a casting or arm c4, the lower end of Which is inclined outwardly and downwardly at an angle to the cup e and to a position a short distance from the lower end of tube e3, and with said end of said casting is connected a short arm or IOO of the tank I.

casting e5, which extends at an angle to the casting or arm e4, the inner end of which extends in the direction of and to Within a short distance of the lower end of tube e3. side of the arm or casting e4, near the side of the receptacle'e, is a transverse perforation e6, which receives the end of the pipe b4, and which perforation extends about half Way through the-said arm. Within the arm e1 is a channel or passage-e7, Which extends from the perforation e6 downwardly within the casting e5. In the casting e5, extending from the outer end nearly to the inner end of said casting, is a screw-threaded perforation e8, Which communicates with the passage e7 and in which perforation is a screw threaded valve-stem e9 of the needle-valve, which is seated at 612 in the end of the perforation es, the needle-valve extending through a smallersized opening 614, extending toward the tube e3. Upon the o uter end of the stem e9 is a hand Wheel 615. In the receptacle or cup e is a removable perforated cap el6 for the distribution of the gas flames. With the upper bent end of the branch b3 of the pipejoint b is connected one end of a pipe f', the other end of which pipe extends horizontally to a position directly beneath the chamber ci in the receiver C and is Wound spirally to form the coil or retort F, the other end of the pipe extending from the coil being connected With the opening g in the side of a vertical casting orthree-Way pipe-joint G, Which is screw-threaded internally and provided with a screw-threaded valve-stem g, the inner end of which stern closes the opening g to the coil of pipe F. With the upper end of the pipe-joint Gr is connected one end of a short length of pipe g2, the other end of -Whicl1 pipe extends through the bottom of the receiver C into the chamber c4. With the bent upper end of the branch b of the joint b is connect-ed one end of a pipe b5, the other end of which pipe extends to a position beneath the coil of pipe or retort F, and with said end is connected a burner ll-I, which is precisely the same in construction as the burner E, heretofore described, and which burner II is arranged a short distance beneath the coil or retort F.

I is a compressed-air tank arranged in position near the tank A. -Between the tanks A and I is arranged an air or gas pressure regulator I of the ordinary and Well-known description. With the inlet to regulator I is connected one end of a pipe i', the other end of Which pipe extends through the top e With the inlet to regulator I is connected one end of a pipe iX, the other end of Which pipe extends through the top c1, of tank A.

Near the tank I is an air-compressing pump K of the ordinary construction and which is provided With a piston-rod k and handle 7c. At the bottom of the pump K is a pipe k2, which extends Within the tank I and through which the compressed air is supplied to said In the tank. With the top fi of tank I is connected one end of a pipe i3 for the compressed air, the other end of which pipe extends in an up- Ward direction and is bent at right ang1es,as at '214, and thence extended upwardly nearly to a position in line With the top of receiver C and Within the inlet-opening to an air or gas regulator L, which is the same as regulator I. With the outlet to said air-pressure regulator is connected a separate pipe Z, which extends ihrough the end c of the receiver C Within the chamber c3. Upon a horizontal line with the tank A is shown a gas supply or storage tank N. With the top n of said tank is connected one end of a pipe n, the other end of which pipe extends upwardly to the receiver C and through the end c of said receiver Within the chamber c6. With the said top n is also connected a gas-dstributz regulator I and of the ordinary description.l

With the outlet to the regulator M is connected one end of a pipe n3, which leads to the place of consumption and upon which is shown a branch pipe n4 and a gas-lam p of ordinary description, and these lamps may be of any number and the distribution through any number of branch pipes.

In operation the tank A is supplied with the proper quantity of the iiuid, such as gasolene, the nature of which is Well known to condense after being vaporized in the heretofore employment of the fluid for conversion into gas. The compressed-air pump K is then operated to supply the tank I with compressed air, or this supply may be obtained from any source of compressed air, and a sufficient pressure of air is supplied to the tank A, which exerts f lthrough pipe 3 to the air-pressure regulator L, and a defined amount of air passes into the chamber c4. Heat being applied to the burners E and H, the flame from said burner II heating the coilor retort F and generating gas on said coil, while the heat from the ame of the burner E passes through the flue D,

and the radiation from flue D heats the chamt ber c6, the height of the ame being regulated by the stem of the needle-valve e, the heat from the burner converting the gasolene into gas, which is mixed with the air in passing through the tube e3. The gas generated in the retort or coil F is admitted to the pipejoint G, the valvestem g regulating the quantity desired for admixture with the compressed air, and Which gas passes Within the chamber c4 in the proportion of about ten per cent. of gas to that of ninety per cent. of compressed air, which is admitted through the air-regulator L. The compressed air in chamber c4, which is largely molecular oxygen, passes downwardly from the point of entrance from the pipe Z toward the orifices c7 IIO in the diaphragm c2, While the heated gas, 4Which is lighter and enters the bottom of the receiver, rises to the top of said receiver and passes through the compressed air at difterent angles, the heated gas mixing with the molecular oxygen of the air, which is also increased in temperature, and in the proportion stated passes through the orifices e0 in the diaphragm c3, being subjected to filtration through said orices, and u'pon entering the chamber c(i the gas formed is reheated in circulating around the flue D, and the product is an illuminating-gas of great efficiency and underconstant pressure. This gas passes through the pipe n into the storage-tan k N, in Which the pressure is maintained asin the receiver C and from which its consumption in the lamp is regulated by passing through the regulator M. In the tortuous admission of the gas through the small orifice in the valve G to the chamber e4 of the receiver C in the proper quantity for due ad mixture of the air and gas it Will be observed that While the pressure of air is constant and uniform in the receiver C and the separate compartments of said receiver the quantity oi' air supplied Will be in proportion to the gas consumed-as, for instance, should the number of lamps in a series which are not required for lighting purposes be cut out from the others the pressure of the air in the receiver C will react upon the gas passing into the chamber c3, and thus minimizing the quantity of gas supplied to said chamber, While the admixture in the proper proportions of air and gas is maintained-While,upon the other hand, should the Whole number of lamps be ignited, which causes a large demand for gas upon the tank N, the release of the pressure Within the separate compartments of the receiver also enable the pressure of the air in tank A to cause an increase of supply of the gasolene to the coil F, and consequently a larger amount ot' gas is generated in the coil F and supplied to the chamber c4, thus increasing and decreasing the supply automatically and at the same time maintaining, as heretofore stated, the relative mixing proportions of air and gas at all times.

I may at Willincrease or decrease the pressure of air in the apparatus to meet the requirements ot distance or length of supplypipes, the gas, however, being of great etliciencT and of less cost than other forms of illuminating-gases. I may employ oxygen gas in place of common air When required. The gas may also be supplied from the receiver direct when required.
